La base de recherche de l\u2019organisation environnementale Shelltone Whale Project, situ\u00e9e \u00e0 Cadaqu\u00e9s, est la premi\u00e8re installation au monde <\/strong>d\u00e9di\u00e9e \u00e0 l\u2019\u00e9tude et au d\u00e9veloppement de m\u00e9thodologies de recherche respectueuses des c\u00e9tac\u00e9s<\/strong>.<\/h2>\n


Sous la direction de Pierre Lavagne de Castellan, cette base m\u00e8ne des campagnes en mer r\u00e9guli\u00e8res visant \u00e0 am\u00e9liorer et \u00e0 normaliser des protocoles d\u2019observation des c\u00e9tac\u00e9s permettant de minimiser les perturbations et d\u2019\u00e9viter tout impact n\u00e9gatif sur les animaux dans leur habitat naturel.<\/p>\n

Ces activit\u00e9s de recherche sont fondamentales pour notre organisation, dont l\u2019objectif principal est la conservation des c\u00e9tac\u00e9s par la promotion de pratiques de whale watching responsables et fond\u00e9es sur des bases scientifiques.<\/p> <\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n

Les distances d\u2019approche<\/h1>\n

Les distances d\u2019observation ne peuvent \u00eatre standardis\u00e9es : elles varient selon les esp\u00e8ces et les comportements. Les grands c\u00e9tac\u00e9s suivent g\u00e9n\u00e9ralement des trajectoires rectilignes, ce qui permet d\u2019anticiper leur d\u00e9placement et de maintenir une distance de s\u00e9curit\u00e9. Les dauphins, en revanche, sont impr\u00e9visibles. Ce sont souvent eux qui initient l\u2019interaction, notamment en venant jouer \u00e0 l\u2019\u00e9trave. Dans ces situations, la distance ne peut plus \u00eatre contr\u00f4l\u00e9e. La responsabilit\u00e9 de l\u2019op\u00e9rateur devient alors comportementale : maintenir une vitesse stable, conserver un cap fixe, et ne jamais chercher \u00e0 suivre ou poursuivre les animaux.<\/strong>.<\/p>\n<\/div>\n<\/div>\n<\/div> <\/div>\n<\/div>\n <\/div>\n

Positionnement et angle d\u2019approche<\/h1>\n

L\u2019approche par l\u2019arri\u00e8re est \u00e0 proscrire<\/strong>. Elle surprend l\u2019animal, perturbe sa trajectoire et g\u00e9n\u00e8re un stress assimilable \u00e0 une poursuite. Cette pratique est pourtant encore largement r\u00e9pandue, notamment pour provoquer la plong\u00e9e des grands c\u00e9tac\u00e9s et obtenir la photographie de la queue, souvent per\u00e7ue comme un troph\u00e9e. Nous consid\u00e9rons ces pratiques comme incompatibles avec une observation respectueuse.<\/p>\n<\/div>\n<\/div>\n<\/div> <\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n

L\u2019approche lat\u00e9rale contr\u00f4l\u00e9e<\/h1>\n

L\u2019approche recommand\u00e9e est lat\u00e9rale et progressive.<\/strong> Le bateau se positionne sur un cap parall\u00e8le \u00e0 celui de l\u2019animal, \u00e0 distance. Il ne se cache pas, ne coupe pas la route, ne poursuit pas. Dans cette configuration, il est per\u00e7u comme un \u00e9l\u00e9ment neutre de l\u2019environnement. Ce n\u2019est qu\u2019apr\u00e8s une phase d\u2019observation attentive \u2014 nage r\u00e9guli\u00e8re, absence d\u2019acc\u00e9l\u00e9ration, stabilit\u00e9 du groupe \u2014 que l\u2019on peut envisager un rapprochement tr\u00e8s progressif. Ce rapprochement s\u2019effectue en d\u00e9viant l\u00e9g\u00e8rement le cap jusqu\u2019\u00e0 atteindre la distance de confort de l\u2019animal.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div> <\/div>\n<\/div>\n <\/div>\n

Le renoncement positif<\/h1>\n

Certaines situations interdisent toute approche : pr\u00e9sence de m\u00e8res avec leurs petits, nurseries, phases d\u2019accouplement ou sc\u00e8nes de chasse active. Dans ces contextes, approcher revient \u00e0 perturber un comportement vital<\/strong>. Le capitaine se retrouve alors face \u00e0 une tension classique : respecter l\u2019animal ou satisfaire les attentes des passagers. Nous d\u00e9fendons une troisi\u00e8me voie : le renoncement positif. Il consiste \u00e0 expliquer clairement la situation, \u00e0 faire comprendre pourquoi ne pas intervenir est un acte de respect. Lorsqu\u2019elle est comprise, cette d\u00e9cision est non seulement accept\u00e9e, mais valoris\u00e9e.<\/strong> Le renoncement devient alors positif pour les animaux, pour l\u2019op\u00e9rateur et pour l\u2019exp\u00e9rience elle-m\u00eame.<\/p>\n<\/div>\n<\/div>\n<\/div> <\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n

Depuis 1981, ma passion pour les c\u00e9tac\u00e9s et mes recherches en communication inter-esp\u00e8ces avec les baleines m\u2019ont conduit \u00e0 travailler dans des habitats o\u00f9 ces animaux vivent et se reproduisent. Au fil des ann\u00e9es, j\u2019ai observ\u00e9 l\u2019\u00e9volution du whale watching, qui est pass\u00e9 d\u2019une pratique confidentielle dans les ann\u00e9es 80 et 90, r\u00e9serv\u00e9e aux passionn\u00e9s et aux scientifiques, \u00e0 une activit\u00e9 touristique de masse d\u00e8s les ann\u00e9es 2000.<\/p>\n

Ce d\u00e9veloppement incontr\u00f4l\u00e9 a entra\u00een\u00e9 une prolif\u00e9ration des bateaux dans les zones de vie des c\u00e9tac\u00e9s, avec des approches souvent peu respectueuses, dict\u00e9es par la n\u00e9cessit\u00e9 de satisfaire les attentes des touristes. Les cons\u00e9quences de ce harc\u00e8lement constant se sont rapidement manifest\u00e9es : stress, perte d\u2019app\u00e9tit et de libido chez les animaux, et m\u00eame abandon de certains territoires.<\/p>\n

Malgr\u00e9 les efforts des sanctuaires marins pour r\u00e9guler cette activit\u00e9 \u00e0 travers des chartes et des formations, de nombreux op\u00e9rateurs continuent de ne pas respecter les r\u00e8gles, cherchant des approches spectaculaires et intrusives sans v\u00e9ritable contr\u00f4le.<\/p>\n

Heureusement, j\u2019ai rencontr\u00e9 des op\u00e9rateurs passionn\u00e9s et respectueux, guid\u00e9s par leur amour des c\u00e9tac\u00e9s et non par le profit. Leurs connaissances permettent des approches douces et respectueuses, cr\u00e9ant des rencontres authentiques et apais\u00e9es avec les animaux.<\/p>\n

Le Shelltone Whale Project a pour objectif de r\u00e9f\u00e9rencer et de promouvoir ces op\u00e9rateurs consciencieux, offrant ainsi \u00e0 chacun la possibilit\u00e9 de choisir une exp\u00e9rience en mer harmonieuse et respectueuse des c\u00e9tac\u00e9s. En r\u00e9servant vos sorties via notre organisation, vous soutenez notre mission de promouvoir des pratiques responsables et de prot\u00e9ger les c\u00e9tac\u00e9s des approches intrusives.<\/p>\n<\/div>\n<\/div> <\/div>\n<\/div>\n\n

The research base of the environmental organization Shelltone Whale Project, located in Cadaqu\u00e9s, is the world\u2019s first facility<\/strong> dedicated to the study and development of cetacean-friendly research methodologies<\/strong>.<\/h2>


Under the direction of Pierre Lavagne de Castellan, this base conducts regular sea campaigns aimed at improving and standardizing cetacean observation protocols to minimize disturbance and avoid any negative impact on animals in their natural habitat.<\/p>

These research activities are fundamental to our organization, whose primary objective is the conservation of cetaceans through the promotion of responsible, science-based whale watching practices.<\/p>\n

OUR METHOD<\/h1>\n\"\"\n

Our areas of operational research<\/h1>

From our base in Cadaqu\u00e9s, we develop and test in real-life conditions protocols to improve whale watching practices<\/strong>, with a clear objective: minimize human impact on cetaceans<\/strong>.<\/p>\n

Approach distances<\/h1>

Observation distances cannot be standardized: they vary according to species and behaviour. Large cetaceans generally follow straight trajectories, which enables them to anticipate their movements and maintain a safe distance. Dolphins, on the other hand, are unpredictable. They are often the ones who initiate interaction, notably by coming to play at the bow. In such situations, distance can no longer be controlled. The operator's responsibility then becomes behavioral: maintain a steady speed, stay on a fixed course, and never try to follow or chase animals<\/strong>.<\/p>\n\"\"\n\"\"\n

Positioning and approach angle<\/h1>

Do not approach from the rear<\/strong>. It surprises the animal, disrupts its trajectory and generates stress akin to pursuit. However, this practice is still widespread, notably to provoke the diving of large cetaceans and to obtain photographs of the tail, often perceived as a trophy. We consider these practices incompatible with respectful observation.<\/p>\n

Controlled lateral approach<\/h1>

The recommended approach is lateral and progressive.<\/strong> The boat positions itself on a course parallel to that of the animal, at a distance. It doesn't hide, it doesn't cross the road, it doesn't chase. In this configuration, it is perceived as a neutral element in the environment. It is only after a phase of careful observation - regular swimming, absence of acceleration, stability of the group - that a very gradual approach can be envisaged. This approach is made by slightly deviating course until the animal's comfort distance is reached.<\/p>\n\"\"\n\"\"\n

Positive renunciation<\/h1>

Certain situations prohibit any approach: presence of mothers with their young, nurseries, mating phases or scenes of active hunting. In these situations, approaching means disrupting vital behaviour<\/strong>. The captain is faced with a classic tension: respecting the animal or satisfying passenger expectations. We advocate a third way: positive renunciation. This involves clearly explaining the situation, and explaining why not intervening is an act of respect. When this decision is understood, it is not only accepted, it is valued.<\/strong>. Renunciation then becomes positive for the animals, for the operator and for the experiment itself.<\/p>\n

This research forms the basis of the Shelltone Whale Project method\u00a0and contribute to the development of whale watching practices that are respectful, non-intrusive and sustainable.<\/strong><\/h2>\n

TAKE ACTION TO PROTECT CETACEANS<\/h1>

BY CHOOSING THE RIGHT OPERATOR FOR YOUR OUTING\u00a0<\/h1>\n Discover responsible operators <\/a>\n\"\"\n

Pierre Lavagne De Castellan<\/h1>\n

Marine bioacoustician - Ethologist - Founder of Shelltone Whale Project<\/h5>\n

Since 1981, my passion for cetaceans and my research into inter-species communication with whales have led me to work in habitats where these animals live and reproduce. Over the years, I've watched whale watching evolve from a confidential practice reserved for enthusiasts and scientists in the 80s and 90s, to a mass tourism activity in the 2000s.<\/p>

This uncontrolled development has led to a proliferation of boats in cetacean living areas, with approaches that are often disrespectful, dictated by the need to satisfy tourist expectations. The consequences of this constant harassment quickly became apparent: stress, loss of appetite and libido in the animals, and even abandonment of certain territories.<\/p>

Despite the efforts of marine sanctuaries to regulate this activity through charters and training courses, many operators continue to flout the rules, seeking spectacular and intrusive approaches with no real controls.<\/p>

Fortunately, I have met passionate and respectful operators, guided by their love of cetaceans and not by profit. Their knowledge enables them to take a gentle, respectful approach, creating authentic, peaceful encounters with the animals.<\/p>

Shelltone Whale Project aims to list and promote these conscientious operators, offering everyone the chance to choose a harmonious, cetacean-friendly experience at sea. By booking your outings through our organization, you support our mission to promote responsible practices and protect cetaceans from intrusive approaches.<\/p>\n\"\"","_links":{"self":[{"href":"https:\/\/www.shelltonewhaleproject.org\/fr\/wp-json\/wp\/v2\/pages\/10219","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.shelltonewhaleproject.org\/fr\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.shelltonewhaleproject.org\/fr\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.shelltonewhaleproject.org\/fr\/wp-json\/wp\/v2\/users\/14"}],"replies":[{"embeddable":true,"href":"https:\/\/www.shelltonewhaleproject.org\/fr\/wp-json\/wp\/v2\/comments?post=10219"}],"version-history":[{"count":19,"href":"https:\/\/www.shelltonewhaleproject.org\/fr\/wp-json\/wp\/v2\/pages\/10219\/revisions"}],"predecessor-version":[{"id":11986,"href":"https:\/\/www.shelltonewhaleproject.org\/fr\/wp-json\/wp\/v2\/pages\/10219\/revisions\/11986"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.shelltonewhaleproject.org\/fr\/wp-json\/wp\/v2\/media\/11333"}],"wp:attachment":[{"href":"https:\/\/www.shelltonewhaleproject.org\/fr\/wp-json\/wp\/v2\/media?parent=10219"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
